MT9042B

The MT9042B Multitrunk System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization signals for multitrunk T1 and E1 primary rate transmission links. The MT9042B generates ST-BUS clock and framing signals that are phase locked to either a 2.048MHz, 1.544MHz, or 8kHz input reference.

The MT9042B is compliant with AT&T TR62411 Stratum 3, 4 and 4 Enhanced, and ETSI ETS 300 011. It will meet the jitter tolerance, jitter transfer, intrinsic jitter, frequency accuracy, holdover accuracy, capture range, phase slope and MTIE requirements for these specifications.
